[0002] The gluing and stapling machine is an intelligent automatic production equipment that can bend, glue and glue cardboard into shape to make cartons. Therefore, this equipment is often used in the field of commodity packaging.

[0003] The gluing and stapling machine processes the cardboard through various structures in multiple steps, including creasing. The so-called creasing is to press an indentation on the originally flat cardboard, making it easier for the cardboard to bend at the indentation so that the cardboard can be folded into a three-dimensional carton.

[0004] The conventional creasing structure generally uses a roller to press an indentation on the surface of a cardboard during its movement, such as a multi-pass creasing structure of a gluing and nailing machine with publication number CN218838780U.

[0005] The cardboard itself has a certain thickness. When the cardboard is pressed down, the two sides of the cardboard are easily warped due to the pressure, thereby affecting the processing effect of the indentation. However, in the prior art, there is no structure that can prevent the cardboard from warping up. Utility Model Content

[0006] The utility model aims to provide a multi-channel pressing structure of an all-in-one gluing and nailing machine, which presses the surface of the cardboard with an annular airbag to tightly fix the edge positions of the cardboard, thereby preventing the two sides of the cardboard from warping up and thus avoiding interference with the pressing operation process.

An annular airbag is fixedly provided on the outer end of the connecting belt. The speed of the annular airbag is the same as the speed of the conveyor belt.

[0010] Furthermore, a driving motor for driving the rotating wheel assembly is fixedly provided on one side of one of the movable plates away from the rotating wheel assembly.

[0011] A movable sleeve is provided between the two movable plates, and a first connecting rod is fixedly provided at one end of the movable sleeve. One end of the first connecting rod is connected to one of the extrusion wheels on one of the movable plates, and a second connecting rod is provided on the other extrusion wheel symmetrical to the extrusion wheel on the other movable plate, and one end of the second connecting rod is inserted into the interior of the movable sleeve.

[0012] Furthermore, a base is provided at the bottom of the conveyor belt, and the two frames are fixed on the top of the base.

[0013] Furthermore, multiple rollers are provided between the two frames, and the rollers are connected by transmission belts. A transmission motor for driving the rollers to rotate is fixed on one of the frames, and two transmission pulleys are provided on the frame. The two transmission pulleys are connected by belts.

DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] The utility model provides Figure 1-8 The multi-track pressing structure of the integrated nail gluing machine shown in the figure includes two frames 1, a conveyor belt 2 for transporting cardboard is provided between the two frames 1, two symmetrically arranged movable plates 3 are provided on the top of the conveyor belt 2, and multiple rotating wheel assemblies 8 are provided on one side of the movable plate 3, and the rotating wheel assembly 8 is located between the two movable plates 3.

[0030] The rotating wheel assembly 8 includes a wheel axle 803 rotatably connected to the movable plate 3, and a connecting disk 804 is fixedly provided at one end of the wheel axle 803 away from the movable plate 3. An extrusion wheel 802 is provided on the connecting disk 804 through bolts, and the size of the extrusion wheel 802 on the same movable plate 3 gradually increases from front to back.

[0031] A connecting belt 16 is provided on one side of the movable plate 3, and a pulley 801 is fixedly provided on the outer end of the wheel shaft 803. The pulley 801 is located between the extrusion wheel 802 and the movable plate 3. All the pulleys 801 on the same movable plate 3 are connected by the connecting belt 16. The pulleys 801 located at both ends of the connecting belt 16 play a driving role and can rotate synchronously with the connecting belt 16 at all times. The middle pulley 801 mainly supports the connecting belt 16, but also has a rotation function. Only when it is in close contact with the connecting belt 16, the middle pulley 801 will rotate under the action of friction. In this way, it can support the movement of the connecting belt 16 without interfering with it. An annular airbag 9 is fixedly provided on the outer end of the connecting belt 16. The speed of the annular airbag 9 is the same as the speed of the conveyor belt 2. The annular airbag 9 is elastic and can play a buffering role when it comes into contact with the cardboard.

[0032] The unprocessed cardboard is moved by the movement of the conveyor belt 2. At the same time, the annular airbag 9 on the movable plate 3 is also driven to rotate. The direction of rotation of the annular airbag 9 is opposite to that of the conveyor belt 2 so that the cardboard can be clamped between the rotary assembly 8 and the conveyor belt 2. When the cardboard moves to the rotary assembly 8, the cardboard is squeezed by the squeezing wheel 802, and the squeezing wheel 802 forms an indentation on the cardboard. Since the squeezing wheel 802 located further back is larger, the squeezing wheel 802 that first contacts the cardboard forms a shallower indentation on the cardboard. As the cardboard continues to move backward and contacts the squeezing wheel 802 behind, the indentation will gradually deepen, avoiding damage to the cardboard caused by excessive squeezing at one time. While the indentation is being processed, the connecting belt 16 and the annular airbag 9 are driven by the pulley 801 to move. The annular airbag 9 is pressed on the surface of the cardboard. The annular airbag 9 is closer to the edge of the cardboard than the pulley 801, so that the two side edges of the cardboard can be pressed and fixed during the indentation process, preventing the two sides of the cardboard from warping up, thereby preventing it from interfering with the creasing operation process.

[0033] The wheel assemblies 8 on the two moving plates 3 rotate synchronously. Figure 3 、 4 As shown, a driving motor 12 for driving the wheel assembly 8 is fixed on one side of one of the movable plates 3 away from the wheel assembly 8. The wheel assembly 8 directly driven by the driving motor 12 is the wheel assembly 8 located at one end of the connecting belt 16, rather than the wheel assembly 8 in the middle position.

[0034] A movable sleeve 13 is provided between the two movable plates 3, and a first connecting rod is fixedly provided at one end of the movable sleeve 13. One end of the first connecting rod is connected to one of the extrusion wheels 802 on one of the movable plates 3, and a second connecting rod is provided on the other extrusion wheel 802 symmetrical to the extrusion wheel 802 on the other movable plate 3. One end of the second connecting rod is inserted into the movable sleeve 13. The cross-sections of the first and second connecting rods are both rectangular. The two wheel assemblies 8 connected by the first and second connecting rods are the wheel assemblies 8 located at the end of the connecting belt 16.

[0035] The wheel assemblies 8 on the same movable plate 3 are connected to each other under the action of the connecting belt 16, and the wheel assemblies 8 on the two movable plates 3 are connected by the movable sleeve 13 and the first and second connecting rods. Therefore, when one of the wheel assemblies 8 is driven by the driving motor 12, the second connecting rod can be extended and retracted inside the movable sleeve 13. On the premise of playing a connecting role, it can also adapt to the different distances between the two movable plates 3 and will not interfere with the adjustment of the distance between the two movable plates 3.

[0036] During use, the conveyor belt 2 plays a role in transportation. In order to increase the support strength of the conveyor belt 2, as shown in FIG. Figure 1 、 2 As shown in , 8 , a base 7 is provided at the bottom of the conveyor belt 2 , and the two frames 1 are fixed on the top of the base 7 .

[0037] A plurality of rollers 10 are provided between the two frames 1, and the rollers 10 are connected by a conveyor belt 2. A conveyor motor for driving the rollers 10 to rotate is fixed on one of the frames 1, and two transmission pulleys are provided on the frame 1, and the two transmission pulleys are connected by a belt. The conveyor motor drives one of the transmission pulleys to rotate, thereby rotating the other transmission pulley, and the other transmission pulley and one of the rollers 10 rotate, so that the conveyor belt 2 also moves and transports the cardboard. The roller 10 directly driven by the conveyor motor is the roller 10 located at the end of the conveyor belt 2, not the roller 10 in the middle position. Except for the rollers 10 at both ends of the conveyor belt 2, the rollers 10 in the other middle positions only play a supporting role and do not interfere with the movement of the conveyor belt 2. The principle is the same as that of the pulley 801 in the middle position.

[0038] The cardboard needs to be clamped between the conveyor belt 2 and the wheel assembly 8 to form an indentation, which requires the conveyor belt 2 to have sufficient support strength for the cardboard. Therefore, multiple rollers 10 are arranged on the inside of the conveyor belt 2. The rollers 10 support the conveyor belt 2 on the inside, so that the conveyor belt 2 has sufficient support strength for the cardboard.

[0039] In order to adjust the distance between the two moving plates 3, as shown in FIG. Figure 1-3As shown, both frames 1 are provided with a threaded push rod 5 that passes through the frame 1. The threaded push rod 5 is connected to the frame 1 through a thread. A hand wheel 6 is fixedly provided at one end of the frame 1. By rotating the hand wheel 6, the threaded push rod 5 can be driven to rotate, and the threaded push rod 5 can move after rotating.

[0040] The other end of the threaded push rod 5 extends between the two frames 1 and is provided with a slide 11 through a bearing. The slide 11 is connected to the movable plate 3 on the same side as the threaded push rod 5 through a slide rail. The slide 11 can slide up and down relative to the movable plate 3, so that the movable plate 3 can move up and down relative to the threaded push rod 5 without interfering with the height adjustment of the movable plate 3.

[0041] Rotating the handwheel 6 can drive the threaded push rod 5 to rotate, causing the threaded push rod 5 to move horizontally, and the threaded push rod 5 can push the movable plate 3 to move horizontally, thereby adjusting the position of the movable plate 3 and the rotating wheel assembly 8, and then adjusting the position of the indentation on the cardboard to adapt to cardboards of different widths.

[0042] In order to adapt to different thickness of cardboard, such as Figure 7 As shown, a top plate 4 is provided between the two frames 1, and two adjustment plates 14 are provided at the bottom end of the top plate 4 through a slide rail. The two adjustment plates 14 are respectively located directly above the two movable plates 3. The adjustment plates 14 and the corresponding movable plates 3 are connected by two cylinders 15. The height of the movable plate 3 and the wheel assembly 8 can be adjusted by the extension and retraction of the cylinder 15 to adapt to cardboards of different thicknesses.

[0043] Two horizontally sliding adjustment plates 14 are connected to the corresponding movable plates 3 through cylinders 15. The adjustment plates 14 can move horizontally synchronously with the movable plates 3, and the extension and retraction of the cylinders 15 can control the height of the movable plates 3 and the rotating wheel assembly 8, thereby controlling the distance between the conveyor belt 2 and the rotating wheel assembly 8 to adapt to cardboards of different thicknesses.

[0044] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
